Abstract

PURPOSE:To smoothly and readily take out cut lawn grass wastes by disposing power- transmitting mechanism for transmitting the power from an engine to a sweeping-up device in a state of the mechanism deviated at the lower portion on either of both the left and right sides of a grass-collecting container to enable the dumping of the grass-collecting container in a lateral direction on the center of a pivotally supporting shaft located on the opposite side of the transmitting mechanism. CONSTITUTION:When an operator operates a steering lever 5 to allow a frame to run for a cleaning work of lawn grasses, the cut lawn grass wastes upward swept with a sweeping-up device 1 disposed at the front portion of the frame are stored in a grass-collecting container 2 through a duct 3. When the grass-collecting container 2 is filled with the lawn grass wastes, the running of the frame is stopped and the grass-collecting container 2 is dumped to discharge the collected grass wastes. The grass-collecting container 2 is re-set to the first position and the cleaning work is again continued. Since a power-transmitting mechanism 6 for transmitting the power from an engine to the sweeping-up device 1 is located at a place deviated on either of the lateral sides of the grass-collecting container 2, it is not required that the grass-collecting container 2 is located at a high position and changed into a complicated shape, and since the grass-collecting container 2 is dumped on a pivotally supporting shaft located on the opposite side of the power-transmitting mechanism 6, the cut lawn grass wastes can be perfectly discharged.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a lawn cleaning machine that collects and cleans grass debris scattered on the lawn due to lawn mowing, etc., and is useful for lawn management in parks and lawn producers. It is used for lawn care, etc.

(Prior Art) As a lawn cleaning machine, there is, for example, one having a structure described in Japanese Utility Model Publication No. 56-45329. This lawn cleaning machine is equipped with a riding control section in the front part of the machine body for a worker to board and operate, a sweeping device in the lower part of the machine, a grass collection container in the rear part of the machine body, and a grass collecting container in the rear part of the machine body. It has a structure that communicates with the grass collecting container through a duct, and the whole structure is quite large.

(Problems to be Solved by the Invention) The present invention is a small lawn cleaning machine that can sweep up and clean grass debris over the entire left and right width of the machine, lower the height of the machine to perform stable running, and collect grass. The purpose is to enable smooth and easy removal of grass waste collected in a container.

(Means for Solving the Problems) Therefore, in the present invention, a sweeping device 1 for sweeping up grass debris is provided in the front part, and a grass collecting container 2 and the sweeping device 1 are provided at the front and rear center of the machine body. In a lawn cleaning machine, the transmission mechanism 6 for transmitting power from the prime mover 4 to the sweeping device 1 is connected to the grass collection container by a separable duct 3, and has a prime mover 4 mounted at the rear and a control device 5. The lawn cleaning machine has a structure in which the grass collecting container 2 can be dumped laterally around a pivot shaft 7 on the opposite side to the transmission mechanism 6.

(Operations and Effects of the Invention) A worker located at the rear of the machine moves the machine while operating the control device 5 to clean the lawn. The grass debris swept upward passes through the duct 3 and is collected in the grass collecting container 2. When the grass collection container 2 is filled with grass debris, the machine stops running, moves the grass collection container 2 to the left and right to discharge the grass debris, and returns the grass collection container 2 to its original position. The aircraft will continue to operate and clean the lawn.

In this way, the grass debris swept up by the sweeping device 1 installed at the forefront of the machine body is blown directly into the grass collecting container 2 via the duct 3, so that the grass debris can be swept over the entire left and right width of the machine body. This results in a smooth flow of grass debris and no clogging.

In addition, since the transmission mechanism 6 that transmits power from the prime mover 4 to the sweeping device 1 is located at the bottom of one of the left and right sides of the grass collecting container 2, the position of the grass collecting container 2 is not raised and the grass can be collected. Since the grass container 2 is dumped around the pivot shaft 7 provided on the opposite side of the transmission mechanism 6 without complicating the shape of the grass container 2, the grass debris in the grass container 2 can be completely removed. This means that it can be discharged.

(Example) Next, an example of the present invention will be described with reference to the drawings.
